Letters Patent No. 93,585, dated August 10,1869.

IMPROVEMENT 1N AXE.

The Schedule referred to in these Letters Patent and makingpart of thesame.

To all whom it may concern.:

Be it known that I, JACOB H. BEIDLER, of Adrian, in the county ofLenawee, a-nd in the State of Michigan, have invented certain new anduseful Improvements in Axes; and do hereby'declare that the following isa full, clear, and exact description thereof,

i. reference being had to the accompanying' drawings,

and to the letters of reference marked thereon.

Jlhe nature of my invention consists in providing one or both sides ot'an axe with a series (if-grooves,

or their equivalents, for the purpose of' removing friction andatmospheric pressure.

In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring ,to the annexed drawings, whichform a part of this specification, and in which- `Figure 1 is a sideview; and '1 v Figure 2, a cross-section. l A represents an axe, made inany of the known and usual ways, and of any material and size desired.

The sides of the axe are provided with a seriesloff perpendicular orother-shaped grooves or ilutes,a a, or their equivalents, commencing asnitabledistance above'the edge of axe, and extending any desired lengthupward. Y l The axe herein described may ne made by rolling the blank inthe desired shape, and the grooves or corrugations therein made when theblank is thus rolled; or, the grooves lmay be cut into the axe, after itis formed, by any suitable device or machinery.

The axe may also be cast of steel, with the grooves,-

or equivalent devices, cast all at one time.

A machine may be formed with steel lingers, for cutting or milling thegrooves in the body of the axe, after the same has been formed by any ofthe known processes; or, the spaces may be ground out by smallgrindstones or emery-wheels.

I do not wish to be understood as confining myself to any mode orprocess for making the axe, as many different methods maybe applied toaccomplish the result desired.

The advantages of such grooves or flutes on an axe are obvious.

It will be seen that a portion of the outer surface of the aXe isremoved; consequently, when the axe enters the wood, there isless'friction, that is, there is less surface where friction can beproduced, and hence, it is evidentthat thesame amount of power willdrive an axe, thus uted, further intothe 'wood than one constructed inthe usual manner.

Further, when an axe is driven into the'wood, it is v sometimes verydiiiicult to remove the same, on accountof the suction, or atmosphericpressure. This is partially obviated by these flutes or grooves, as theair is admitted through the same downward, and thus a great portion'ofthe suction is removed.

I do not confine myself to any partcula-1' shape, size, or angle of thegrooves or flutes; nor do I claim any specific number of such ilutes, asthat must,A in a great measure, be regulated by the size and thicknessof the axe.

Having thus fully. described my` invention,

' What I claim as new, and desire "to secure by Letters Patent, is-

The axe herein described, having a series of grooves on one or bothsurfaces, substantially as and for the purposes specified. l

In testimony that I claim the foregoing, I have hereunto set my hand,this 1st day of March, 1869.

' JACOB H. BEIDLER.
